Costa Rica is one of those countries where the onward ticket rule actually gets enforced, both by the airline that flies you there and by the immigration officer when you land. I learned this the hard way watching a fellow backpacker get pulled aside at SJO because her "ticket" was a Google Flights PDF with no booking reference. A dummy ticket, also called an onward ticket, is a real PNR reservation you can book quickly without purchasing a full-price flight. Here's what travellers heading to Costa Rica actually ask.

Do I Really Need an Onward Ticket for Costa Rica?

Short answer: yes, and they actually check. Costa Rica's immigration law requires that visitors be able to demonstrate they intend to leave before their permitted stay expires. For most nationalities that's 90 days, but here's the catch: Costa Rica participates in the CA-4 Agreement with Guatemala, El Salvador, and Honduras. That 90-day allowance is shared across all four countries. If you've been road-tripping through Guatemala for five weeks before flying into San José, you've got around 35 days left in Costa Rica, not 90.

Both your airline and the DGME officer on arrival will ask for proof. This means a confirmed departure ticket with a real PNR, not a screenshot, not a booking you haven't fully confirmed. The UK government's Costa Rica travel advice sets out the current entry conditions and CA-4 stay limits for British nationals.

What Counts as a Valid Onward Ticket for Costa Rica?

This is the question that trips people up most. Here's a table of what works and what doesn't:

Document type Has a PNR? GDS-queryable? Accepted at SJO/LIR?
Dummy ticket (confirmed reservation) Yes Yes (Amadeus/Sabre/Galileo) Yes
Fully paid return or onward flight Yes Yes Yes
OTA soft hold (unconfirmed) No No No
Google Flights screenshot No No No
Price-comparison site PDF No No No
Confirmed bus ticket (land border) N/A N/A Sometimes, at land crossings

The key is that the DGME officer can enter a booking reference into a GDS terminal and see whether a confirmed flight exists under your name. If they can't find it, you go to secondary inspection. A dummy ticket from My Dummy Ticket gives you a real confirmed PNR that resolves in the GDS the same way a fully paid ticket does.

Does the Onward Ticket Have to Leave from Costa Rica?

Not necessarily, and this surprises a lot of people. If your plan is to travel overland from Costa Rica to Panama via the Paso Canoas border crossing, then fly home from Tocumen International (PTY) in Panama City, that exit flight from Panama works as your onward proof. The immigration officer is looking for a plausible departure from the region, not specifically a flight from SJO or LIR.

Some travellers doing a Central American loop book a dummy ticket from Guatemala City or Cancún as their exit, and that works too, provided the route makes sense with the itinerary they describe at the desk. Just make sure the exit date is realistic relative to how long you're saying you'll stay. If you tell the officer you're staying 60 days but your ticket leaves in 20, they'll ask more questions.

How Long Does a Dummy Ticket Stay Valid, and When Should I Book It?

For a Costa Rica trip, book your dummy ticket about 24 to 48 hours before your departure flight. The PNR enters the GDS almost immediately and can be queried by the airline check-in agent within minutes.

The question I hear most: "what if my booking expires before I actually travel?" Dummy tickets are typically live for 72 hours to a few days, depending on the issuing airline's ticketing deadline. The PNR only needs to be valid at two moments: when the airline checks at check-in, and when the DGME officer checks on arrival. Once you're through both checkpoints, the ticket can expire without affecting your stay at all.

Can I Use a Bus Ticket or Ferry Booking Instead of a Flight?

For land border crossings like Paso Canoas (Costa Rica-Panama) or Peñas Blancas (Costa Rica-Nicaragua), some DGME officers will accept a confirmed bus ticket as proof of onward travel. It's not guaranteed and depends on the individual officer.

At airports, it's a different story. Airlines consult IATA Timatic for their check-in requirements, and Timatic generally calls for flight evidence. The check-in agent at Miami International or JFK isn't going to accept a Tico Bus booking confirmation to clear you for a flight to SJO. A dummy flight ticket is the safest option for airport check-in and for arrival at SJO or LIR. It also works at land borders.

Frequently Asked Questions

What if I'm entering Costa Rica from Panama by land?

The DGME post at Paso Canoas still applies the entry requirement, but accepts a wider range of onward proof. A confirmed onward flight from any point is the safest bet. A bus ticket out of Costa Rica might also work. Carry something confirmed, even if it's not a flight.

Does a return ticket I already have count as my onward ticket?

Yes, if it's in a confirmed status (HK) in the GDS and hasn't been cancelled or expired. Check the booking status before you travel. If it shows as cancelled or if it departed in the past, it won't help you.

What happens if the DGME officer doesn't believe my ticket is real?

They'll query the PNR directly in the GDS. A real dummy ticket comes back confirmed. A screenshot, PDF without a booking reference, or unconfirmed hold comes back blank. That's when secondary inspection starts. The safest thing is to have a real PNR.

Can I just book a cheap refundable flight and cancel after I arrive?

Yes, that works, and it's essentially what a dummy ticket does, but at a lower price point. The risk with booking a cheap refundable flight yourself is that you need to check the ticketing deadline carefully: some airlines cancel unticket reservations within 24 hours, and if that happens before your check-in, you're back to having nothing.

Will my dummy ticket affect my authorised length of stay in Costa Rica?

No. The exit date on your dummy ticket is proof of intent, not a hard deadline. The DGME grants you a permitted stay period on entry (up to your CA-4 remaining days). That stay period is what governs when you need to leave, not the specific date on your ticket.
